Serial No. 85,394.

To all whom it may concern:

Be it known that I, WILLIAM B. Honor., a lcitizen of the United States, residing at Charlotte, in the county of Mecklenburg and State of North Carolina, have invented certain new and useful Improvements in Systems of Distribution for Humidifying, Heating, and Air-Conditioning Apparatus; and I do hereby declare the following to be a full,

` scopic materials than has been possible heretofore. L

-In the accompanying drawings, which form part of this specification Figure 1 represents a sectional perspective elevation of an ordinar room with a loom, such as is used in weavingA cloth.

Fig. 2 represents 4a sectional elevation of the end ofthe room and the floor of the mill showing a distributing pipe.

Fig. 3 represents a sectional of Fig. 2 on line 3 3.

Fig. 4 represents a plan view tributer.

Reference being had to end elevation of the disthe drawings^and the-designating characters thereon, 1 indicates a duct of galvanized iron or other suitable material for conveying air from a fan or other suitable `source of supply (not shown) but heated and moistened to any dethe temperature and 'the humidityf the air sired degree; This main duct may extend across the mill, Vand thence by lateral ducts .1 valong or through lthe mill, directly under,-

neath the line of looms or other machinery on which is placed vthe .hygroscopic material that it is desired to humidity.

3 indicates atemperature and humidity controller through which the air from duct l is `forced and 'passed over thermo-responsive members, and by means of whichboth entering the duct 1 is controlled to any desired degree. Such a humidity controller is illustrated and described in U. S. Patent 1,075,197 granted October 7, 1913, 4Patent No. 856,944 of June 1l, 1907, and, consequently does not need further description.

6 indicates a loom, the warp threads of which itis desired to keep moistened so as to prevent breakage of the warp and produce.

better, and smoother work.

7 indicates the beam on which the Warp threads are wound. 8 indicates the outlet from duct 1, by means of which the humidiied and conditioned air from the duct 1- is let. up

through the pipe 9 and discharged against the beam 7.

It is well known that hygrostatic substances hold an amount'ot` moisture. substantially dependent upon the' humidity'and temperature of the air which surrounds them. For instance, -in the case of cotton, if the temperature and humidity of a room in which cotton is placed, is accurately known,

-thezmoi'sture content of the cotton stored in that room can be ascertained from a tabulated chart quitc as accurately as by drying the cotton out and estimating the percentage of moisture by mathematical calculation. The same applies to other fibers, suchas silk and wool, and to hygrosco ic materials such as grain, tobacco and the l e. Infact, it, appears to be a hysical law that any hygroscopic materi standing in a room with cer- .tain conditions of temperature and humidity, absorbs or gives oil' more or less moisv ture` until its moisture content is exactly 'what the temperature and humidity conditions of the room indicate for that particuthe warp on a loom, we can maintain those warp threads at any desired moisture content, depending upon the humidity and temperature setting of the regulator 3, and similarly, by somewhat changing the shape of the outlet of diffuserl 8, we can attach above it either skeins orcones of cotton or various withstood at times by operatives in the room.

And, furthermore, it allows a distinctly I local conditioning process and can be carrled on 1n a much simpler, more economical and quicker manner by using the blast of material is used above the diuser.

air or by merely allowing these substances to stand quiet in a dead atmosphere.

rlhe practical operation of this apparatus, merely depends upon setting regulator 3 so that the temperature and humidity of the air carried through the duct l and discharged through uiduser 8 shall be of the required character to produce the desired moisture content in whatever hygroscopic lit is, of course, evident that the diuser should be made of the proper shape to get a uniform distribution or volume of air along its entire length, which, of course, in the case of moistening a beam on the loom would be extended as shown on the drawing. ln moistening cotton in the form of cones, skeins or other Well known forms, a somewhat different shape of outlet would be necessary, dependin upon the exact shape of the product to e conditioned, and 1n handling tobacco, grain and other hygroscopic materials, even still different shaped outlets would be desirable.

Furthermore, it is evident that in such distribution it would not be necessary, although it is convenient, to have the distributing pipe underneath the floor, inasmuch as anv arrangement for distributing a properly conditioned current of air against the hygroscopic material under treatment will fall withln the scope of this invention.

Having thus fully described my invention, what I claim iS:-

In an apparatus for supplying conditioned air to hygro'scopic material undergoing treatment, the combination with a conduit having a nozzle arranged to direct the air upon such material, a temperature and humidity controller arranged in said conduit and operating upon the condition of vsuch air or any change therein to control and regulate the temperature and humidity of the air to the optimum condition of such hygroscopie material.

In testimony whereof I aiix my signature in presence of two witnesses.

WILLIAM B. HODGE.
